Stage 3 6.7L Cummins Performance Head

Our Stage 3 Cummins Performance Head is designed for extreme high performance. It includes everything in our Stage 2 Cummins Performance Head, along with a D&J Stage 3 Billet Intake Manifold, oversize super alloy intake and exhaust valves, thread-in soft plugs in the head, titanium valve spring retainers, and heavy-duty extra-large intake seats. This head can only be used with 6.7L (4.212 inch) bore or larger.

Key Features:

  • Upgraded Valve Seats: Heavy-duty extra-large intake seats address the issue of stock intake seats falling out in 1000+ hp trucks, ensuring durability and reliability.
  • Thread-In Soft Plugs: Prevents soft plugs under the valve cover from coming out and filling the crankcase with coolant.
  • Billet Intake Manifold: Designed to keep the factory rail, lines, MAP sensor, fuel filter housing, air horn, and throttle position sensor. This ensures more even air distribution, preventing hotspots and potential piston melting.
  • Increased Airflow: Intake flow increased to 300 CFM, compared to the stock 165 CFM, providing enhanced performance.
  • Oversize Super Alloy Valves: 1.500-inch super alloy intake valves and 1.450-inch super alloy exhaust valves for improved durability and performance.

Detailed Process:

  • Complete Disassembly: The head is completely disassembled, and all soft plugs are removed.
  • Cleaning and Blasting: Thorough cleaning and blasting to ensure a pristine surface.
  • Crack Check: Performed to ensure structural integrity.
  • New Components: Installation of all-new bronze guides and heavy-duty extra-large intake seats on both intake and exhaust sides.
  • 5-Axis CNC Porting: Performed for optimal airflow.
  • Thread-In Soft Plugs: Installed under the valve cover for enhanced reliability.
  • High-Performance CNC Valve Job: Precision CNC valve job performed for enhanced performance.
  • Resurfacing: The head is resurfaced to meet exact specifications.
  • Thorough Cleaning: Comprehensive cleaning process to eliminate all debris.
  • Expert Assembly: Assembled with all new valve seals, thread-in soft plugs, 115# springs, and titanium retainers.
